Assessing and Diagnosing Patients With Anxiety Disorders, PTSD, and OCD

By Day 7 of Week 4

Complete and submit your Comprehensive Psychiatric Evaluation, including your differential diagnosis and critical-thinking process to formulate primary diagnosis.

Incorporate the following into your responses in the template:

  • Subjective: What details did the patient provide regarding their chief complaint and symptomology to derive your differential diagnosis? What is the duration and severity of their symptoms? How are their symptoms impacting their functioning in life?
  • Objective: What observations did you make during the psychiatric assessment?
  • Assessment: Discuss the patient’s mental status examination results. What were your differential diagnoses? Provide a minimum of three possible diagnoses with supporting evidence, listed in order from highest priority to lowest priority. Compare the DSM-5-TR diagnostic criteria for each differential diagnosis and explain what DSM-5-TR criteria rules out the differential diagnosis to find an accurate diagnosis. Explain the critical-thinking process that led you to the primary diagnosis you selected. Include pertinent positives and pertinent negatives for the specific patient case.
  • Reflection notes: What would you do differently with this client if you could conduct the session over? Also include in your reflection a discussion related to legal/ethical considerations (demonstrate critical thinking beyond confidentiality and consent for treatment!), health promotion and disease prevention taking into consideration patient factors (such as age, ethnic group, etc.), PMH, and other risk factors (e.g., socioeconomic, cultural background, etc.).

Psychosocial History

Mrs. I. F., a 47-year-old married woman, has exhibited significant emotional and behavioral changes following a school shooting that occurred near her community approximately three weeks ago. According to her husband, her behavior and emotional state changed abruptly after the incident. She is now preoccupied with the event, frequently watching television news reports, and actively seeking information about the shooting. Her husband reports that she spends most of the day and night watching news coverage.

      I.F reports significant sleep disturbances, including difficulty initiating and maintaining sleep, with a total sleep duration of 4 to 5 hours per night. She also notes a decreased appetite since the incident. These symptoms have persisted for three weeks and are adversely affecting her daily functioning and quality of life. Mrs. I. F. denies any prior psychiatric, substance use, or mental health treatment. There is no family history of mental illness. She has no known drug allergies. History of hysterectomy. No legal history is reported. The onset of symptoms following a traumatic event may indicate a trauma- and stressor-related disorder.

Mental Status Examination

Mrs. Flanagan appeared well-dressed and well-groomed. She was oriented to person, place, time, and situation. Speech was articulate, coherent, and purposeful. Mood was described as anxious, with affect congruent to mood. Thought processes were logical and organized, though primarily focused on the recent school shooting and its impact. No hallucinations, delusions, paranoia, or other indicators of psychosis were observed. Memory was intact, and cognitive functioning appeared grossly normal. Judgment and insight were intact. She denied suicidal ideation.

Differential Diagnoses

Post-Traumatic Stress Disorder (PTSD) (ICD-10: F43.11) appears to be the most likely diagnosis. According to the DSM-5-TR, PTSD can develop after someone experiences or witnesses’ death, serious injury, or violence, and is linked to symptoms like intrusion, avoidance, negative thoughts and feelings, and changes in arousal or reactivity (Brock, 2023). Mrs. I.F was psychologically affected by a nearby school shooting and later developed chronic anxiety, hypervigilance, sleep problems, loss of appetite, and felt overwhelmed by trauma-related information. The unusual timing between the traumatic event and the start of her symptoms suggests that this is likely a case of PTSD.

      Acute Stress Disorder (ASD) (ICD-10: F43.0) is diagnosed when symptoms manifest within three weeks following a traumatic event. According to the DSM-5-TR, ASD develops within three days to one month after trauma and is characterized by symptoms such as intrusion, negative mood, dissociation, avoidance, and arousal. Mrs. I.F. exhibits several indicators of ASD; however, she also presents symptoms suggestive of emerging Post-Traumatic Stress Disorder (PTSD), including persistent trauma-related thoughts and hyperarousal. ASD remains a provisional diagnosis, as her symptoms have not persisted beyond one month.

     Generalized Anxiety Disorder (GAD) (ICD-10: F41.1) was also considered. The DSM-5-TR states that GAD involves worry or anxiety about different activities and events for most days over at least six months. Mrs. Flanagan does have anxiety, sleep problems, and trouble functioning. However, all her symptoms are linked to a single traumatic event in her past, not to many different situations. She also does not meet the six-month duration requirement. For these reasons, GAD does not fit her clinical picture and is not the main diagnosis.

The timing, severity, and context of symptom development were systematically evaluated to determine the primary diagnosis (Atri et al., 2025). Positive findings included trauma exposure, Acute anxiety, hypervigilance, hypo-appetence, sleep disturbances, and significant impairment in daily functioning. Negative findings included the absence of psychotic symptoms, substance use, depression, generalized anxiety, or prior psychiatric history. The temporal association between symptom onset and the school shooting strongly indicates a trauma-related disorder. Posttraumatic stress disorder (PTSD) (ICD-10: F43.11) is the most probable diagnosis based on symptom duration, symptomatology, and clinical presentation.

Reflection Notes

I would like to collect more detailed information on intrusive memories, nightmares, avoidance behaviors, emotional numbing, and dissociative symptoms. The use of a validated screening tool, such as the PTSD Checklist for DSM-5, can support a more accurate diagnosis and provide a baseline for tracking treatment progress. Additionally, gathering further patient history from the husband may clarify the extent of functional impairment and behavioral changes.

Confidentiality and informed consent are important, but other legal and ethical considerations also apply. It is essential to minimize the risk of retraumatization during trauma discussions while still gathering information that will be needed for accurate diagnosis and effective treatment planning.

Cultural sensitivity is important, as Mrs. Flanagan’s Northern Irish background may affect her perception of trauma, coping strategies, and engagement with mental health services.        Psychoeducation on trauma responses, sleep hygiene, stress reduction, limiting exposure to distressing media, and building social support are key health promotion strategies (Lotzin et al., 2023). Early intervention helps prevent symptom escalation and improves outcomes. Consider additional factors such as age, stress, socioeconomic status, and available support networks, as these may influence recovery and treatment adherence.
